Entelechia is a fictional character associated with Arknights, a tactical mobile game and anime-adjacent franchise set in the dystopian world of Terra. As a character name, Entelechia appears to function as a singular mononym rather than a clearly separated first and last name. The term evokes philosophical ideas of realization or fulfillment, which fits the series’ tendency toward symbolic naming. Within the broader Arknights setting, Entelechia is presented as part of the game’s character roster and worldbuilding, contributing to the narrative atmosphere and faction-driven conflicts.
